I found this in a friends basement he was cleaning out and am trying to
find out what it is.
It looks sort of like a key and has a moveable dial on the side that
register 1/2 a degree with each turn of the shaft stickiing out of the end.
the dial on the front can be rotated to a new postion to use as a reference
point. markings on front are

I did a google search and came up empty
Mike got it right. It is a speed gauge. There was one back on the farm and
we used it once or twice to check the fan speed on a combine (The fan that
separates chaff from grain). Later, grandpa went and bought a similar device
with a rubber tip and a
large dial that read in RPMs. Switched as his eyes were going bad and had a
hard time reading the first gauge.

Hee, hee, I'll jump in ;^)
RPM gauge ( I have one) You press the head against a rotating shaft and feel
the bump on the dial pass under your thumb as it rotates. WIth the help of a
second handed watch, you can get a close idea of teh shaft RPM.
